First time doggy style in a porn cinema: I was fucked and cummed on by a stranger while on the horse

The booth door in the porn theater closes with a soft click. My heart pounds against my ribs as I lean over the narrow stool. This is it. My first doggy-style fuck with a complete stranger. I feel him approaching, his hands gripping my hips, and then a hard, unfamiliar head presses against my wet pussy. With a deep thrust, he slides all the way inside me. I cry out softly with pure pleasure and pain as he takes me mercilessly from behind, deeper and harder each time. His rhythm becomes frenetic, his thrusts lashing my ass, and then, with a loud, rumbling groan, I feel him stiffen inside me. A wave of hot cum floods my deep pussy, filling me completely. He stays inside me for a moment before pulling out, his cock disappearing from my cunt. I remain bent over, his juice slowly running down my thighs, while I still feel the sensation of his stranger fucking me.
